This was my first thought when seeing the current submission too. I have no problem with reposts, but one thing I would question is when one provides the date in the title. 2011 is too recent to do so? I don't know, for me that seems borderline. It is not in the guidelines. What do we think? Ought we to have a "[Repost]" tag? Is someone posting a link to the previous submission in the comments sufficient? I think I lean towards the latter, but agree with my sibling that an explanation of the link is preferred.
